Application iled December 13, 1915. Serial No. 66,543.

To all whom t may concern.:

Be it known that I, MAYER LEON GOLD- MAN, a citizen of the United States, residing at the borough of Brooklyn, city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Closures for Bottles and the like, of which the following is a specification.

My invention relates to devices of the crown cap type for use in sealing bottles and other vessels and my objects are the production of a cap of the accepted, standard type .which can be applied by existing machines without material change yet so modilied that it| may be thereafter removed and re-applied by hand to the bottle making a tight seal.

A further object is the production of a bottle for use with my cap which enables the cap to be removed by any flat imple` ment without necessitating the use of a special tool.

By reason of their cheapness and eiliciency crown caps have come into almost universal use in sealing bottles the contents of which are used immediately, the cap being thrown away asincapable of repeated use by reason of the deformation in removing it from the bottle.

My invention contemplates the repeated use of such crowns on bottles a portion of whose contents are used at a time and which are-then reseale'dfor future use and which have heretofore been stoppered with ordinary long corks. The caps of my invention may also be used as the old style were, that is once only, as they produce a more reliable seal and are freer from leakers than the standard crown cap.

lln the drawing Figure 1 is a sectionaly view of my cap before applying to the' bottle and shows it as initially formed; Fig. 2 is a sectional View of the preferred form of bottle neck especially adapted for use with my cap; and Fig. 3 is a sectional view 'of the cap applied to a bottle.

rlhe cap, like the ordinary crown, consists of a metal shell 1 with the approximately flat top 2, the depending side walls 3 and the corrugated flange 4. A sealing gasket 5 is preferably held inside the shell 1 in any suitable manner, the use of the adhesive collet 6 being customary. lin some cases the sealing disk may be dispensed with and the unlined shell used in stopperlng a vessel.

The shell differs from those heretofore known in the peculiar shape of its side walls and corrugations. rlFhe side walls are bulged out at 6 instead of being straight and the intermediate portions of the inner 'corrugations 7 at the locking points formmg the smallest internal diameter of the shell are carried in below the bulge as is best shown in Fig. 1. In other words the side walls are initially conformed to the shape of the bead-like portion of the bottle lip above their smallest diameter and their smallestl internal diameter at the locking points of the corrugations is less than the greatest diameter of the bead on the bottle. The bottle 8 has the bead 9 at the outside of the lip and located thereunder is a ledge 10 having a flat upper surface which is just eitftpyvt the edge of the cap when it is on the In use the-cap is seated on the lip with thev sealing pressure plunger of the capping. machine which not only compresses the sealing disk, when one is used, but also forces the small diameter of the shell over the large diameter of the bead with a snap action due to the natural resiliency of the metal. 'llhe skirt or flange is then bent inwardly under the bead as best shown in Fig. 3. As before stated a portion of the shell being initially shaped to conform to the shape of the upper part of the bead on the bottle there is less deformation lof the cap in applying than there is in the ordinary cap with the straight side walls which must be shaped to the bead by the applying tool.

To remove the cap it is only necessary to place a flat implement on the rim 10 and by a twisting motion lift the cap which is not the cap is merely pushed down on the lip of the bottleh when the contracted portion of the metal shell will spring over the largest part of the bead 9 and draws itself into sealed position. In other words, as the form of that portion of the shell contacting with the lip above the largest diameter of the bead substantially conforms to the shape of the bead at that part the snap past the center action which occurs in re-applying the cap by hand draws it into place and fully reseats it with a seal which will protect the contents indefinitely against loss by evaporation, leakage or accident.

1. A vessel seal comprising a resilient,

non-rupturable shell provided with a top, side walls and a continuous, radially corrugated depending {iange adapted for use on a vessel with an exterior bead on the lip-V therein, adapted for use on a vessel with an exterior bead on the lip thereof, the internal,

upper portion 'of the shell corresponding to the upper portion of the exterior beaded lip above its largest diameter initially substantially conforming to the shape of that portion of the lip with which its contacts and the smallest internal diameter of the shell being below the largest diameter of the lip and initially less than said lip diameter.

8. ln combination, a vessel seal comprising a resilient, non-rupturable shell provided with a top, side walls and a radially corrugated, depending fiange and a vessel provided With a bead on the exterior of the lip and a flat topped ledge thereunder, the internal,l upper portion of the shell corresponding to the upper portion of the exterior beaded lip above its largest diameter initially substantially conforming to the shape of that portion of the lip with ,which it contacts and the smallest internal diameter of the shell being below the 'largest diameter of the lip and initially less than said lip diameter.

In testimony whereof I have aiixed my signature in resence of two witnesses.
